Review of Additive Manufacturing by Direct Metal Laser Melting

Office of Nuclear Regulatory Research
The NRC has been informed that additively manufactured (AM) parts are being considered for applications in the operating fleet as early as 2018.  In 2017, industry prototyping efforts involved use of the direct metal laser melting (DMLM) method to manufacture parts for reactor components.  The NRC Office of Nuclear Regulatory Research is beginning to evaluate the technology to gain insight into any technical issues that must be addressed to assure safety and reliability of specific DMLM-produced components that may be accepted by the NRC, including design, precursor materials, finished material properties, structural integrity, nondestructive evaluation, and quality assurance.  This poster also discusses the emergence and harmonization of relevant codes and standards activities.  This poster will give an overview of NRC findings and preliminary recommendations related to additive manufacturing via DMLM.
